Class
    Foam::alphatBoilingWallFunctionFvPatchScalarField

Description
    This boundary condition provides a thermal wall function or the turbulent
    thermal diffusivity for walls on which a wall boiling fvModel is in
    operation. The controls for the boiling model are not specified in this
    condition; they are provided to the wall boiling fvModel. The presence of
    this condition is used, however, to determine on which walls boiling takes
    place.

Usage
    Example of the boundary condition specification:
    \verbatim
    <patchType>
    {
        type            alphatBoilingWallFunction;
        libs            ("libmultiphaseEulerFvModels.so");
        value           uniform 0;
    }
    \endverbatim
